Hi, This is an updated patch series with a fix applied to what is now 3/5 for a bug that was reported by Dmitry (thanks!) having triggered with his x86-64 setup and then nailed down by Linus (also thanks!). Additionally as suggested by Linus a fix has been added, for a preexisting problem with the routing table not being verified to stay whole within the BIOS memory range, that has become 1/5, expanding the whole series from 4 to 5 changes now. In the course of that addition a couple of coding style issues have been consumed, shrinking what has now become 5/5. The cover letter has been updated accordingly throughout. First 1/5 handles $PIR PIRQ routing tables that lack router device information, fixing the inability to route interrupts with a system using the SiS85C497 ISA bridge. Then 2/5 adds support for the $IRT PIRQ routing table format invented by AMI before Microsoft has come up with its own $PIR format. These formats are very similar to each other, but the $IRT format does not provide for router device information, so this change relies on 1/5. It has turned out needed to route interrupts with a system using the ALi M1487 ISA Bus Controller device, discussed earlier on in a discussion thread around: <https://lore.kernel.org/linux-pci/61377A45.8030003@xxxxxxxxx/>. This change has been verified with an artificially created $IRT table. Then 3/5 adds a range check for Then 3/4 corrects our link value interpretation for said M1487 device according to Nikolai's findings with his system reported here: <https://lore.kernel.org/linux-pci/61428EDF.9030203@xxxxxxxxx/>. Finally 4/4 corrects a couple of coding style issues around though not immediately within code changed by 2/4 so as to make the style consistent. See individual change descriptions for further details. Credit to Michal (cc-ed) for helping me chase documentation for the $IRT table format. Please apply. Maciej
